This
number from Ralph Edwards
Productions had a trio of
players try to be the first to
spell "Knockout" by
identifying the one element not
belonging among a quartet of
words or phrases. Each
identification earned a
contestant one letter, who could
then earn another letter by
telling the relationship among
the remaining three elements, or
try to win two extra letters by
challenging another contestant
to do the same. There was a
catch in the second option in
that the challenged player could
get the two letters instead of
the challenger if he or she made
a correct identification.
The
game winner then played a
two-tiered bonus round where on
the first level he or she tried
to guess the topic connecting
three clues revealed one at a
time. A correct guess was worth
$500 on the first clue, $300
after two clues, and $100 after
three clues. Correct
identification on any level led
to a chance to win 10 times that
amount by playing the same game
but getting only one clue to
name the category. Hosted by
